#### Solution

(i)  $\left( \frac{a}{3} + 1, b - \frac{2}{3} \right) = \left( \frac{5}{3}, \frac{1}{3} \right)$

By the definition of equality of ordered pairs, we have:

$\left( \frac{a}{3} + 1, b - \frac{2}{3} \right) = \left( \frac{5}{3}, \frac{1}{3} \right)$

$\Rightarrow \left( \frac{a}{3} + 1 \right) = \frac{5}{3} \text{ and } \left( b - \frac{2}{3} \right) = \frac{1}{3}$
$\Rightarrow \frac{a}{3} = \frac{5}{3} - 1 \text{ and } b = \frac{1}{3} + \frac{2}{3}$
$\Rightarrow \frac{a}{3} = \frac{2}{3} \text{ and } b = 1$
$\Rightarrow a = 2\text{ and } b = 1$
